BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to a display device for a vehicle to indicate various status data values regarding the conditions of an engine therefore, and in particular to a display device for a watercraft to indicate various status data values regarding the conditions of an outboard motor, such as engine speed, trim angle, cooling water temperature, battery voltage, and oil level.
2. Description of the Related Art
Conventional display devices for a watercraft, which indicate various status data values of outboard motor conditions, are known. Such devices provide special display regions for indicating watercraft speed or engine speed, as well as trim angle of the outboard motor. Oil level meters are generally provided independently to indicate the oil level, such as by the lighting position among the three lamps. One such display device is described in Japanese Patent Document JP-B-Hei 6-027978.
However, such devices do not clearly specify how to indicate other status data values regarding the outboard motor conditions, including, for instance: cooling water temperature, cooling water pressure, battery voltage, and oil pressure.
Additionally, a problem with such conventional display devices is that dedicated meters must be provided for every type of status data to be displayed. Therefore, as the number of status data to be displayed is increased, a larger installation space is necessary to accommodate all the display devices for a watercraft. In addition, as these meters are of a built-in type, all of them would come into an operator's view at any time, requiring a substantial work load and mental strain on the operator's part for visually recognizing the information on the meters.
SUMMARY OF THE INVENTIONTo solve the above problems, a display device is provided for a watercraft to indicate various status data related to the conditions of the outboard motor (e.g., cooling water temp, engine speed, trim angle, oil level, etc.), while allowing the reduction of the device size, and the improvement of the visual recognition ability.
One aspect of the present invention involves a display device for a watercraft to indicate various status data values regarding the conditions of an outboard motor, such as cooling water temperature, battery voltage, and oil level. The display device comprises a dot matrix display provided as a part of display region, in which dots capable of being turned on and off are arranged in the form of matrix, and the status data values are indicated by means of the lighting pattern of the dots.
Another aspect of the present invention involves a display device for a watercraft to indicate various status data values regarding the conditions of an outboard motor, such as cooling water temperature, battery voltage, and oil level. The display device comprises a display region having a dot matrix display including a plurality of dots, the dots being arranged in the matrix and adapted to be selectively turned on and off to form a pattern, the pattern adapted to illustrate at least one status data value. The display device also comprises an information mark display section disposed proximal the dot matrix display and configured to display at least one information mark corresponding to the at least one status data value, the information mark identifying a category of the status data. The display device further comprises means for varying the display position of the at least one information mark indicated on the information mark display section and the display position of the at least one status data value on the dot matrix display.
Accordingly, a display device for a vehicle (e.g., watercraft) can be provided that can display the desired data selected by the watercraft operator or the software responsible for collection and management of information regarding the boar's operation.
These and other features, aspects and advantages of the present invention will now be described in connection with a preferred embodiment of the invention, in reference to the accompanying drawings. The illustrated embodiment, however, is merely an example and is not intended to limit the invention. The drawings include the following eight figures.

In the illustrated embodiment, the information mark display section 42 is divided into grids arranged in the form of matrix. Predetermined information marks can be lighted on or off freely in each grid. Turning on or off of the light for the information mark can be set up variably for each grid. Accordingly, a display device can advantageously be provided with only the desired information marks being lighted for improved recognition of the status data values.
As shown in
In the embodiment shown in
In
In one preferred embodiment, the display section 14 is configured with a liquid crystal display. Since high visibility is required anytime day or night from the display, the display 14 should be a transmissive liquid crystal display having a back light of intensive brightness, or a reflective liquid crystal display with a front light. Alternatively, the display section 14 can include dotted, light-emitting diodes of intense brightness and arranged in the form of matrix.
Besides the scale, a warning symbol depicted by the lighting pattern of the dot-matrix may be displayed in each region 41 of the dot matrix display 21. For instance in the region 41 at the intermediate section in
Arrangements are made so that the plurality of status data values regarding the conditions inside of the outboard motor 13, as the subject of such display, are transmitted to the display device 12 via the LAN. In the display device 12, arrangements are made to select the status data values necessary for the display among the data values from the outboard motor 13, and to display them at the predetermined position in the display section 14.
While the outboard motor 13 is in its operating condition, revolution speed data, trim position data, and other status data values regarding the conditions of the outboard motor 13 are transmitted from the outboard motor 13 side to the display device 12 via the LAN, as shown in
Similarly, the CPU 17 performs the display process for other status data values. In the course of such data processing, the CPU 17 makes reference to a screen configuration designation chart, an information mark display designation chart, and a selective screen designation chart, which have been stored in nonvolatile memory contained in the display device 12.
In one preferred embodiment, the screen configuration designation chart stores more than two patterns of screen configuration for the dot matrix display 21. Specifically, the screen configuration designation chart is a data base in the form of a matrix, in which each column corresponds to the category of status data values such as water pressure, water temperature, battery voltage, oil level, oil pressure, accumulated engine operating hours, and accumulated trip hours, while each row corresponds to the screen configuration numbers for the dot matrix display 21. Further, two (2) kinds of information are stored in each field, determined by specifying the row and the column of this database.
The first one of the two (2) kinds of information is to identify if the relevant status data value should be displayed or not, and to specify the form of display regarding the relevant screen configuration number. The value of the first information denotes that the relevant status data value will not be displayed if it is “ ”(i.e., blank). The relevant status data value will be displayed in the form of scale if it is “S.” The relevant status data value will be displayed in characters by using a series of letters or numerals if it is “C.” Alternatively, the relevant status data value will be displayed in both scale and characters if it is “SC”. The second one of the two (2) kinds of information is to specify in which section of the dot matrix display 21 the relevant status data value should be displayed.
In addition, the total number of the status data values displayed for each screen configuration number is stored in the second column of the screen configuration designation chart.
Table 1 shows an example of the screen configuration designation chart.
The information mark display designation chart stores the information regarding the type of information marks to be displayed in the information mark display section 42, and its display position for each screen configuration. That is, the information mark display designation chart is a data base in the form of a matrix, in which each column corresponds to the types of information marks, such as: the cooling water pressure mark 22, the cooling water temperature mark 23, the water accumulation mark 24, the battery mark 25, the oil level mark 26, the oil pressure mark 27. Each row corresponds to the screen configuration numbers. Further, each field determined by specifying the row and the column of this database stores the information for designating in which column and row in the information mark display section 42 the relevant information mark should be displayed in regard to the relevant screen configuration number. If this field if blank, the relevant information mark is not displayed for the relevant screen configuration number. For example, the water accumulation mark 24 among the above-mentioned six (6) information marks is not displayed in the normal condition. The water accumulation mark 24 blinks as a warning only when water accumulation is detected in the fuel filter. Table 2 shows an example of the information mark display designation chart.
The selective screen designation chart stores the screen configuration numbers to which the screen may be switched by means of the mode selecting switch 15. Table 3 shows an example of the information mark display designation chart.
Initially, the CPU 17 refers to the first row of the selective screen designation chart to acquire the screen configuration number allocated to the selective screen 1. Then, it refers to the row in the screen configuration designation chart that corresponds to the acquired screen configuration number. Referring to the information values in each column of the applicable row, and if the status data value corresponding to that column needs to be displayed, the CPU 17 transmits the relevant information value to a dot-matrix display processing section 31. At this time, the CPU 17 simultaneously transmits the total number of the status data values displayed in the relevant screen configuration number. This is because the height of the rectangular region 41 of the dot-matrix section 21 in which the relevant data value is displayed, is determined based on the total number of status data values to be displayed.
Also, the CPU 17 refers to the row in the information mark display designation chart that corresponds to the screen configuration number of the selective screen 1. Referring to the information value in each column of the row, and if the information mark corresponding to that column needs to be displayed, the CPU 17 transmits the relevant information value to an information mark display processing section 31 that is responsible for carrying out the information mark display process.
Display processing sections 31 through 34 receive data from the CPU 17, perform predetermined processing to create data for display, and transmit them to a display driver. Then, the display driver outputs the control signal for display to the display section 14.
As the contents of the screen configuration designation chart, the information mark display designation chart, and the selective screen designation chart are specified as shown in Tables 1 through 3, the display condition on the display section 14, as shown in
As has been described so far, since the screen configuration on the display section 14 of the display device 12 can be set up freely by the discretional setting of the contents in the screen configuration designation chart, the information mark display designation chart, and the selective screen designation chart, the display device 12 for a watercraft can be provided to display various status data related to the conditions of the outboard motor 13, while achieving a device of reduced size and improved visual recognition ability.
As described above, the screen configuration designation chart in Table 1, and the information mark display designation chart in Table 2 stores plural patterns of screen configuration on the dot matrix display 21, and the information mark display section 42 of the display section 14. This allows a user to select their desired screen configuration by providing appropriate user interface. An example of such user interface, which is composed using the mode selecting switch 15 and the set switch 16, is described below
Tables 4-6 show an example of contents for the selective screen designation chart in the nonvolatile memory of the display device 12.
In the normal condition, that is, when CPU 17 is carrying out no interruption processing that arises as a user actuates the mode selecting switch 15 or set switch 16, the screen configuration number specified as selective screen 1 is referenced to by the CPU 17, as described above. Then, CPU or controller 17 refers to the row corresponding to the screen configuration number in the screen configuration designation chart and in the information mark display designation chart, and controls the screen display on the display section 14 in accordance with the contents of the referred row.
Now, the behavior when interruption processing is performed as a user actuates the mode selecting switch 15 is described. Every time the mode selecting switch 15 is actuated (e.g., pressed down) by a user, the CPU 17 cyclically switches the screen configuration on the multi-display section 20 as selective screen 1→selective screen 2→selective screen 3→selective screen 4→selective screen 1. That is, the CPU 17 changes cyclically the position of the row to which it refers on the selective screen designation chart as; second row→third row→fourth row→first row, and so on. As the position of the referenced row is changed, the CPU 17 displays the current status data values on the display section 14 in accordance with the screen configuration number of the referring row. For instance, when the contents of selective screen designation chart in Table 4 is applied, the screen display based on the screen configuration number 5 is presented in normal condition. However, every time the user presses down the mode selecting switch 15, the screen configuration on the display section 14 changes cyclically as screen configuration number 14→screen configuration number 15→screen configuration number 13→screen configuration number 5, and so on. A series of screen configurations switching as described above are shown in
When the mode selecting switch 15 or set switch 16 is not actuated (e.g., pressed down) for a predetermined period of time, e.g. for 10 seconds, the CPU 17 restores the processing under normal condition. In other words, it presents the screen display based on the screen configuration number specified as the selective screen 1.
Next, the behavior when the set switch 16 is actuated by a user is described. Assume one of the selective screens is displayed as a result of actuating (e.g., pressing down) the mode selecting switch 15 by a user. Here, each time the set switch 16 is actuated by a user, CPU 17 switches the screen configuration cyclically as screen configuration number 1→screen configuration number 2→screen configuration number 3→ . . . screen configuration number 16→screen configuration number 1, indicating the current status data values on such selective screen.
If the mode selecting switch 15 is actuated by the user at some point in the process, the screen configuration number presented at that time shall be applied to the selective screen. In other words, the contents of the row corresponding to the switched selective screen number in the selective screen designation chart are overwritten on the screen of the relevant screen configuration number.
For instance, when the contents of selective screen designation chart in Table 5 is applied, the screen display is switched as shown in
In addition, the data value display for the engine revolution speed and the trim position is suspended on each screen of the display section 14 shown in
One embodiment of a user interface configured by using the mode selecting switch 15 and the set switch 16 for switching the selective screen of multi-display section 20 and for setting the screen configuration of each selective screen has been described in the foregoing sections. However, the configuration of user interface is not limited by any means to what has been described above.
As have been explained in the foregoing sections, users can switch the display of the multi-display section 20 on the display section 14 at any time and over the plural number of screens. In addition, users can set the screen configuration of each selective screen in any desirable manner. Thus, there is no need for squeezing a lot of status data values display into one screen, and users can allocate the data on each screen so as to provide the highest visibility to each user. With this arrangement, the display device 12 for a watercraft with substantially reduced workload and mental strain required for the visual recognition of the display can be provided.
Now, screen conditions of the display section 14 upon activation of the display device 12 are described in the following sections. When the power to the display device 12 is turned on, the CPU 17 indicates an activation display on the display section 14 for a period of about 1.0 second. From between about 1.0 to 3.0 seconds after the activation, the CPU 17 indicates a test pattern on the display section 14. From between about 3.0 to 4.0 seconds after the activation, the CPU 17 indicates the revolution speed in the revolution speed display section 18, and the trim position in the trim position display section 19, along with the accumulated operation hours and trip hours on the multi-display section 20. From about 4.0 seconds onward after the activation, the CPU 17 refers to a maintenance parameter chart that is included in the nonvolatile memory storing the data related to the maintenance of the outboard motor 13. Then, if any requirement for maintenance is detected, the CPU 17 indicates the message to this effect on the multi-display section 20. If there are plural requirements for maintenance, the maintenance message for each requirement is indicated alternately by switching it at about every 3.0 seconds. Display of the maintenance message continues until the mode selecting switch 15 is actuated (e.g., pressed down) by the user. In one embodiment, the timing for requiring the oil change, the timing for requiring impeller inspection, and other information are registered in the maintenance parameter chart.
If no maintenance requirements are detected, or if the maintenance message display is canceled as the mode selecting switch 15 is pressed down by users while the maintenance message is being indicated from about 4.0 seconds onward after the activation, then transition to the normal mode takes place. That is, the CPU 17 starts the display processing of the status data values to display them on the display section 14, as described above.
As have been described, the display device 12 for a watercraft is provided according to
